Compare image onto itself fails

[francois@lubie.co]

I did a simple test to compare images with themselves, and I get differences. Here is the command line I used:

Code: Select all

find ${TMPDIR} -type f \( -iname \*.gif -o -iname \*.png -o -iname \*.jpg -o -iname \*.jpeg \) -exec compare -metric AE {} {} null: \;

I get mostly results of 0, but sometimes

Version of compare: ImageMagick 6.5.4-7 2012-05-07 Q16 OpenMP
OS: Linux CentOS 6 Kernel 2.6.32-358.14.1.el6.x86_64

Am I doing something wrong or is compare broken? Just to let you know.

This message should be moved to the Users forum or the Bugs forum and not the Wizards Toolkit.

Your version of IM is very old. Can you provide a link to your images?

It works fine in IM 6.8.6.9 Q16 Mac OSX

compare -metric AE rose: rose: null:
0

Try the above command in the command line and let us know what you get?
